A family feud erupts when a rich and lonely old woman, Dorothy Hepple, is found dead in her home.
Dorothy leaves all her money and property to her beloved cats, rather than her nephew, Harry, and niece, Caroline.
Her body lay undiscovered for two weeks and the cause of death is undetermined, but the fact that her cats were deliberately locked in the house, forcing them to start eating their owner's remains and any evidence, makes Jack suspicious.
There appears to have been no love lost between the late Ms Hepple and her neighbour, Tim Cuswell. Meanwhile her carer, Dale , seems to have been devoted to her, his motives are questionable.
When the last of Dorothy's feline beneficiaries dies, her estate suddenly comes up for grabs.
With no shortage of people laying claim to the estate, the team decides to reopen the investigation into Dorothy's death.
